A method for a vehicle includes using sensors in a vehicle seat to detect biometrics of a person sitting in the seat and a vehicle controller determining from the biometrics of the person whether the person requires medical attention. In response to the person requiring medical attention, a request for assistance for the person is broadcasted via a V2X transceiver of the vehicle to medical practitioners of a medical practitioner network who are near a location of vehicle during the broadcasting. The medical practitioner network includes the person as a subscriber and medical practitioners as providers. Alternately, in response to the person requiring medical attention, the vehicle controller uses an autonomous vehicle control system of the vehicle to drive the vehicle to a medical facility.

A passenger's weight measurement device for a vehicle seat includes an upper rail provided on a lower rail that is fixable to a vehicle floor, the upper rail being movable in at least one of rear and front directions; a load sensor fixed onto the upper rail; and a frame provided on the load sensor and below the vehicle seat. In plan view, the load sensor protrudes from the frame in at least one of left and right directions.

A sensor disposition structure in a seat includes a cushion pad and a board-like member which is disposed under the cushion pad. A concave is formed in an upper surface of the board-like member, and a sensor is disposed in the concave.

The present invention is generally related to isolation systems for various seating configurations. The isolation system may comprise a first set of isolators positioned perpendicular to a second set of isolators. The positioning of the first and second sets of isolators may enable the isolation system to exhibit a radial stiffness of at least 350 lbf/inch. The improved radial stiffness of the isolation system may dampen and attenuate the transfer of energy (e.g., vibrations) to the seat, which may facilitate a smoother ride for an operator sitting in the seat.

An occupant detection method includes detecting a load applied to a seat for a vehicle, detecting that an occupant is seated at the seat, holding a local maximum of the load which is detected when the occupant becomes seated, setting a standard value of the load in a state in which the occupant is seated at the seat, and estimating a body height of the occupant on the basis of a comparison between the local maximum of the load and the standard value of the load, wherein when the body height of the occupant is estimated, the larger a difference between the local maximum of the load and the standard value of the load is, the higher body height of the occupant is estimated.

To provide a sensor unit that can be easily attached to and detached from a seat in which a seated occupant is seated, and a seat equipped with a sensor unit. A sensor unit includes a sensor module including a biological sensor that detects a biological signal of a seated occupant, and a wireless communication unit that is connected to the biological sensor to wirelessly transmit the detected biological signal to an outside; and a sensor holder that holds the sensor module. The sensor holder includes a seat attachment portion detachably attached to an attached portion that is provided in a front surface of a seat cushion at a position at which the seated occupant is abuttable against the attached portion.

A conveyance seat includes a seat cushion including a cushion frame serving as a skeleton. The cushion frame includes a body frame made of a frame-shaped body, and a support member bridging one portion and the other portion of the body frame in a predetermined direction and supporting a seated occupant. The support member is provided with a central support portion supporting the seated occupant, side support portions provided at positions outside the central support portion in a seat width direction and extending outward in the seat width direction while inclining, and a shape-holding member extending along outer edge portions of the side support portions and bridging the one portion and the other position of the body frame.

An occupant discrimination system of a vehicle seat includes a load detecting portion disposed on a lower side of a seat and detecting a load acting on the seat; an occupant discrimination portion discriminating a state of an occupant among a no occupant state, adult seated state, and child seat fixed states based at least on a load detected from the load detecting portion and a load continuation duration.

Provided is a vehicle seat fastening structure that enables a reduced length of a bolt for fastening a movable rail and a cushion frame in a spaced-apart manner. The cushion frame includes a bottom wall extending in a seat-width direction and a seat front-rear direction. The nut includes a body having a cylindrical shape and configured to penetrate the bottom wall, a thread groove, and a flange portion projecting radially from the body. A length of the nut along a central axis thereof is greater than a separation distance between an upper surface of the movable rail and an upper surface of the bottom wall of the cushion frame in a state in which no impact is applied to the cushion frame. The flange portion is provided in an area of the nut at a distance from an insertion opening for the bolt greater than the separation distance.

A method for a vehicle includes using sensors in a vehicle seat to detect biometrics of a person sitting in the seat and a vehicle controller determining from the biometrics of the person whether the person requires medical attention. In response to the person requiring medical attention, a request for assistance for the person is broadcasted via a V2X transceiver of the vehicle to medical practitioners of a medical practitioner network who are near a location of vehicle during the broadcasting. The medical practitioner network includes the person as a subscriber and medical practitioners as providers. Alternately, in response to the person requiring medical attention, the vehicle controller uses an autonomous vehicle control system of the vehicle to drive the vehicle to a medical facility.
